This training report provides an introduction to servers. A server is a system that responds to requests across a network to provide network services. Servers can operate on dedicated computers or networked devices. They provide services like file sharing, web hosting, email, printing, and more. Server hardware is optimized for high network throughput and I/O over graphical interfaces. Common server operating systems have features that make them suitable for server environments like advanced security, networking, and backup capabilities. Servers come in different sizes from rack, tower, blade, and more.

2. INTRODUCTION TO SERVER
A server is a system (software and
suitable computer hardware) that
responds to requests across
a computer network to provide, or
help to provide, a network service.
Servers can be run on a dedicated
computer, which is also often
referred to as "the server", but many
networked computers are capable of
hosting servers. In many cases, a
computer can provide several
services and have several servers
running.

3. • The term server is used quite broadly in information technology.
Despite the many server-branded products available (such as server
versions of hardware, software or operating systems), in theory any
computerized process that shares a resource to one or more client
processes is a server. To illustrate this, take the common example
of file sharing. While the existence of files on a machine does not
classify it as a server, the mechanism which shares these files to
clients by the operating system is the server.

4. Similarly, consider a web server application (such as
the multiplatform "Apache HTTP Server"). This web
server software can be run on any capable computer.
For example, while a laptop or personal computer is
not typically known as a server, they can in these
situations fulfill the role of one, and hence be labeled
as one. It is, in this case, the machine's role that
places it in the category of server.

5. In the hardware sense, the word server typically
designates computer models intended for
hosting software applications under the heavy demand of
a network environment. In this server configuration one
or more machines, either a computer or a computer
appliance, share information with each other with one
acting as a host for the other

6. SERVER HRDWARE
• Hardware requirement for servers
vary, depending on the server
application. Absolute CPU speed is
not quite as critical to a server as
it is to a desktop machine.
Servers' duties to provide service
to many users over a network lead
to different requirements such as
fast network connections and high
I/O throughout. Since servers are
usually accessed over a network,
they may run in headless mode
without a monitor or input device.
Processes that are not needed for
the server's function are not used.
Many servers do not have
a graphical user interface (GUI) as
it is unnecessary and consumes
resources that could be allocated
elsewhere. Similarly, audio
and USB interfaces may be
omitted.

7. WHAT SEVER PROVIDES
• In the client/server programming
model, a server is a program that
awaits and fulfills requests
from client programs in the same or
other computers. A given application
in a computer may function as
a client with requests for services
from other programs and also as
a server of requests from other
programs.
• Specific to the Web, a web server is
the computer program (housed in a
computer) that serves
requested html pages or files. A
Web client is the requesting program
associated with the user. The
Web Browser in your computer is a
client that requests HTML files from
Web servers.

8. TYPES OF SERVER
• Application server a server dedicated to running certain software
applications
• Catalog server a central search point for information across a
distributed network
• Communications server carrier-grade computing platform for
communications networks
• Compute server, a server intended for intensive (esp. scientific)
computations
• Database server provides database services to other computer
programs or computers
• Fax server provides fax services for clients
• File server provides remote access to files
• Game server a server that video game clients connect to in order
to play online together

9. TYPES OF SERVER
• Home server a server for the home
• Mail server handles transport of and access to email
• Mobile Server or Server on the Go is an Intel Xeon processor based
server class laptop form factor computer.
• Name server or DNS
• Print server provides printer services
• Proxy server acts as an intermediary for requests from clients
seeking resources from other servers
• Sound server provides multimedia broadcasting, streaming.
• Stand-alone server a server on a Windows network that neither
belongs to nor governs a Windows domain
• Web server a server that HTTP clients connect to in order to send
commands and receive responses along with data contents

10. SERVER OPERATING SYSTEM
• Server-oriented operating systems tend to have certain features
that make them more suitable for the server environment, such as:
• GUI not available or optional
• Ability to reconfigure and update both hardware and software to
some extent without restart
• Advanced backup facilities to permit regular and frequent online
backups of critical data
• Transparent data transfer between different volumes or devices
• Flexible and advanced networking capabilities
• Automation capabilities such as daemons in UNIX and services in
Windows
• Tight system security, with advanced user, resource, data, and
memory protection.

11. Server-oriented operating systems can, in many
cases, interact with hardware sensors to detect
conditions such as overheating, processor and
disk failure, and consequently alert an operator
or take remedial measures themselves.

12. DIFFERENT SIZE OF SERVER
• Rack server
• Tower server
• Miniature (home) servers
• Mini Rack server
• Blade server
• Mobile server

13. CONCLUSION
From the above basic study, Server is a system
(software and suitable computer hardware) that
responds to requests across a computer network to
provide, or help to provide, a network services.
• It has provided a Reduction in usage of paper
Records.
• Communication and security to data has been
increased
• Ease of reliability have been added by server for
users
• Managing data is now much more easier.
